ABSTRACT

The present invention relates to a product package assembly comprising: a plurality of fibrous structure products wherein each fibrous structure product comprises a textured surface; one or more inner packages that surrounds the plurality of fibrous structure products; an outer sleeve fitted over the inner package, the outer sleeve comprising: a. an outside face intended to be displayed to a consumer when the package is displayed for sale, the outside face comprising one or more product feature display areas that represent a product feature of the fibrous structure product; b. an inside face; and c. one or more open sides forming at least one inner package receiving pocket.

FIELD OF THE INVENTION

This invention relates to a consumer product package assembly comprising a plurality of fibrous structure products and more particularly to such a consumer product package assembly having a reinforcing sleeve comprising a product feature display area thereon that represents, identifies, communicates, and/or amplifies, to the consumer, the product feature of the fibrous structure product within the package assembly.

BACKGROUND OF THE INVENTION

Disposable consumer products and packages containing such products are well known in the art. Such products may include, for example, facial tissues, paper toweling, hankies, bath tissue, napkins, placemats, paper plates, etc. Frequently, these products are provided with textured surfaces or other features to enhance product performance and/or to enhance consumer appeal. Consumers, however, may not fully appreciate the actual benefits of the product until he or she sees or uses the actual product. Moreover, consumers prefer to view the product prior to selecting the product for purchase so that they may select an appealing product. In addition, product pakaging, even if transparent, may also conceal some of the specific features, especially the textured features, from the view of the consumers. It would be advantageous therefore, to provide a package assembly that has a product feature display area to maximize visability of the product and/or to represent and communicate the high quality features and benefits of the product to the consumer.

In addition, consumers prefer to purchase multiple rolls of these products at the same time. Therefore, these products are almost exclusively sold in multi-roll packages that are stacked one on top on the other on the store shelves. Such products are generally packaged in a clear, thin, flexible plastic wrap package. Although these packages are generally designed to protect the product from contamination, handling, shipping, and storage of the product, these types of packaging may perforate, tear, or stretch, during handling, may not stack easily, and may not protect the integrity of the product, especially the textured surfaces. Therefore, it would also be advantageous to provide a package assembly that further protects the product during handling, shipping and storage and that provides stable stacking of the multi-roll package or multi-package assembly on the store shelves.

Therefore, the present invention overcomes some of the disadvantages of the prior art by providing a consumer product package assembly comprising a plurality of fibrous structure products, a reinforcing outer sleeve comprising a product feature display area thereon that represents, identifies, communicates, and/or amplifies, to the consumer, the product feature of the fibrous structure product within the package assembly.

DETAILED DESCRIPTION OF THE INVENTION Definitions

As used herein, “paper product” refers to any formed, fibrous structure products, traditionally, but not necessarily, comprising cellulose fibers. In one embodiment, the paper products of the present invention include tissue-towel paper products.

A “tissue-towel paper product” refers to products comprising paper tissue or paper towel technology in general, including, but not limited to, conventional felt-pressed or conventional wet-pressed tissue paper, pattern densified tissue paper, starch substrates, and high bulk, uncompacted tissue paper. Non-limiting examples of tissue-towel paper products include disposable or reusable, toweling, facial tissue, bath tissue, table napkins, placemats, wipes, and the like.

“Ply” or “Plies”, as used herein, means an individual fibrous structure or sheet of fibrous structure, optionally to be disposed in a substantially contiguous, face-to-face relationship with other plies, forming a multi-ply fibrous structure. It is also contemplated that a single fibrous structure can effectively form two “plies” or multiple “plies”, for example, by being folded on itself. In one embodiment, the ply has an end use as a tissue-towel paper product. A ply may comprise one or more wet-laid layers, air-laid layers, and/or combinations thereof. If more than one layer is used, it is not necessary for each layer to be made from the same fibrous structure. Further, the layers may or may not be homogenous within a layer. The actual makeup of a tissue paper ply is generally determined by the desired benefits of the final tissue-towel paper product, as would be known to one of skill in the art. The fibrous structure may comprise one or more plies of non-woven materials in addition to the wet-laid and/or air-laid plies.

The term “fibrous structure”, as used herein, means an arrangement of fibers produced in any papermaking machine known in the art to create a ply of paper. “Fiber” means an elongate particulate having an apparent length exceeding its apparent width. More specifically, and as used herein, fiber refers to such fibers suitable for a papermaking process. “Basis Weight”, as used herein, is the weight per unit area of a sample reported in lbs/3000 ft² or g/m².

“Machine Direction” or “MD”, as used herein, means the direction parallel to the flow of the fibrous structure through the papermaking machine and/or product manufacturing equipment.

“Cross Machine Direction” or “CD”, as used herein, means the direction perpendicular to the machine direction in the same plane of the fibrous structure and/or fibrous structure product comprising the fibrous structure.

“Densified”, as used herein, means a portion of a fibrous structure product that is characterized by having a relatively high-bulk field of relatively low fiber density and an array of densified zones of relatively high fiber density. The high-bulk field is alternatively characterized as a field of pillow regions. The densified zones are alternatively referred to as knuckle regions. The densified zones may be discretely spaced within the high-bulk field or may be interconnected, either fully or partially, within the high-bulk field. One embodiment of a method of making a pattern densified fibrous structure and devices used therein are described in U.S. Pat. Nos. 4,529,480 and 4,528,239.

“Non-densified”, as used herein, means a portion of a fibrous structure product that exhibits a lesser density than another portion of the fibrous structure product.

“Embossing”, as used herein, refers to the process of deflecting a relatively small portion of a cellulosic fibrous structure normal to its plane and impacting the projected portion of the fibrous structure against a relatively hard surface to permanently disrupt the fiber to fiber bonds.

“Laminating”, as used herein, refers to the process of firmly uniting superimposed layers of paper with or without adhesive, to form a multi-ply sheet.

“Textured surface of the fibrous structure product”, as used herein, refers to the incorporation of texture into the fibrous structure product via the converting end of the papermaking process and/or the during the wet end stage of papermaking, including embossing, wet microcontraction, creping, the use of papermaking belts to effect a pattern densified structure, etc., and combinations thereof.

Fibrous Structure Product with Textured Surface

In one embodiment the package assembly of the present invention comprises a plurality of rolls of fibrous structure product wherein at least one roll comprises a textured surface. In another embodiment each roll, of the plurality of rolls of fibrous structured product, comprises a textured surface.

The present invention is equally applicable to all types of consumer paper products such as paper towels, toilet tissue, facial tissue, napkins, placemats, wipes and the like.

The present invention contemplates the use of a variety of paper making fibers, such as, natural fibers, synthetic fibers, as well as any other suitable fibers, starches, and combinations thereof. Paper making fibers useful in the present invention include cellulosic fibers commonly known as wood pulp fibers. Applicable wood pulps include chemical pulps, such as Kraft, sulfite and sulfate pulps, as well as mechanical pulps including, groundwood, thermomechanical pulp, chemically modified, and the like. Chemical pulps may be used in tissue towel embodiments since they are known to those of skill in the art to impart a superior tactical sense of softness to tissue sheets made therefrom. Pulps derived from deciduous trees (hardwood) and/or coniferous trees (softwood) can be utilized herein. Such hardwood and softwood fibers can be blended or deposited in layers to provide a stratified web. Exemplary layering embodiments and processes of layering are disclosed in U.S. Pat. Nos. 3,994,771 and 4,300,981. Additionally, fibers derived from wood pulp such as cotton linters, bagesse, and the like, can be used. Additionally, fibers derived from recycled paper, which may contain any of all of the categories as well as other non-fibrous materials such as fillers and adhesives used to manufacture the original paper product may be used in the present web. In addition, fibers and/or filaments made from polymers, specifically hydroxyl polymers, may be used in the present invention. Non-limiting examples of suitable hydroxyl polymers include polyvinyl alcohol, starch, starch derivatives, chitosan, chitosan derivatives, cellulose derivatives, gums, arabinans, galactans, and combinations thereof. Additionally, other synthetic fibers such as rayon, polyethylene, and polypropylene fibers can be used within the scope of the present invention. Further, such fibers may be latex bonded.

In one embodiment the paper is produced by forming a predominantly aqueous slurry comprising about 95% to about 99.9% water.

Basis Weight Method

Basis weight is measured by preparing one or more samples of a certain area (3000 ft² or m²) and weighing the sample(s) of a fibrous structure according to the present invention on a top loading balance with a minimum resolution of 0.01 g. The balance is protected from air drafts and other disturbances using a draft shield. Weights are recorded when the readings on the balance become constant. The average weight (lbs or g) and the average area of the samples (3000 ft² or m²) are calculated. The basis weight (lbs/3000 ft² or g/m²) is calculated by dividing the average weight (lbs or g) by the average area of the samples (3000 ft² or m²). This method is herein referred to as the Basis Weight Method.

All measurements referred to herein are made at 23±1° C. and 50% relative humidity, unless otherwise specified.
